Written by Laura Chappell

In this course Laura begins from the ground up - beginning with a demonstration of Chanalyzer and the Wi-Spy Adapter used to identify WLAN signal strength and interference. Next, Laura takes you into the world of capturing WLAN traffic using Wireshark - explaining the purpose of the AirPcap adapters and the set-up process to capture and aggregate traffic on multiple channels, create a WLAN-specific profile for the two types of WLAN headers (Radiotap and PPI). You'll learn the tricks to identify the types of WLAN traffic and apply decryption methods to the traffic.
